Description

Technical Field

[0001] This invention relates to the field of drilling technology, and more specifically to a drilling device for metal parts. Background Technology

[0002] Metal parts are processed according to usage requirements to obtain the desired products. Among these processes, drilling is the most common. Traditional drilling equipment, however, limits the user's ability to adjust the drill bit height appropriately based on actual usage conditions, resulting in significant limitations. Furthermore, waste material cannot be effectively collected during the drilling process.

[0003] To address the aforementioned issues, Chinese Patent Publication No. CN213104559U discloses a drilling device for metal parts processing with a waste collection function. The device includes a support platform and a slot. A housing is located on the upper left side of the support platform, and a latch is located in the middle of the lower end of the housing. A slot is located at the lower end of the latch. A protective cover is located on the upper right side of the housing, and a right slider is located on the left end of the protective cover. A groove is located on the inner side of the slider, and a threaded hole is located at the lower end of the slider. A bolt is located at the right end of the threaded hole. A motor is located inside the protective cover, and a drill bit is located in the middle of the lower end of the motor. A clamping seat is located at the lower end of the drill bit, and a support column is located at the lower end of the clamping seat. A base is located at the lower end of the support column. This patent allows for height adjustment of the drill bit according to usage requirements and also enables centralized collection of waste materials.

[0004] The above-mentioned patent has the following problems during actual use: the waste generated from drilling metal parts is metal particles and metal powder, which are mixed together and collected in a collection tank. The metal particles have great recycling value and need to be screened out. Currently, the screening work is mainly done manually, which is labor-intensive and inefficient. In addition, the metal particles may be irregular in shape, which can easily cause hand injuries. Summary of the Invention

[0005] The present invention aims to provide a drilling device for metal parts to solve the problem that existing drilling devices cannot screen metal particles and metal powders in drilling waste.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a drilling device for metal parts, comprising a base and a drilling mechanism for drilling holes in metal parts. The base has sliding grooves on both sides of its top, with movable blocks slidably connected within the grooves. Clamping blocks are provided on the side walls of the movable blocks, and each clamping block has a vertically extending through hole extending to its free end. Each clamping block has a V-shaped box with a top opening at its bottom, with several screening holes on one side of the bottom of the V-shaped box and a discharge port on the other side. The base has a collection trough containing a partition plate, which abuts against the turning point of the bottom of the V-shaped box after lateral movement. The device also includes an adjustment mechanism for adjusting the distance between the two movable blocks.

[0007] The principle and advantages of this solution are as follows: This solution uses an adjusting mechanism to bring two movable blocks closer together, causing two clamping blocks to clamp and position the metal part. During the movement of the movable blocks, the movable blocks drive the V-shaped box to move laterally, causing the bottom bend of the V-shaped box to abut against the partition. Then, the drilling mechanism drills holes in the metal part. Compared with existing technologies, the metal particles and metal powder generated during drilling fall to the bottom left side of the V-shaped box, allowing the metal powder to fall into the collection tank through the screening holes, placing it on the left side of the partition. Meanwhile, the metal particles, guided by the bottom left side of the V-shaped box, move towards the bottom right side, finally falling from the discharge port into the collection tank, placing them on the right side of the partition. This completes the classification and storage of metal powder and metal particles, improving work efficiency and avoiding hand injuries during manual screening.

[0008] Furthermore, the adjustment mechanism includes a chamber formed in the base, a bidirectional screw rotatably connected to the base, and a drive unit for driving the bidirectional screw. The chamber is connected to a slide groove, the bidirectional screw passes through the chamber, and two movable blocks are threadedly connected to both ends of the bidirectional screw. The movable blocks are laterally slidably connected to the chamber.

[0009] With the above setup, the bidirectional screw is driven to rotate by the drive unit, causing the two moving blocks to move closer together.

[0010] Furthermore, the base has a side plate on the top, with an inclined groove on the side plate, and an auxiliary block slidably connected in the inclined groove; the bottom of a single clamping block has a vertical groove, and the vertical groove and the V-shaped box are located on opposite sides of the top of the base; a lifting block is slidably connected in the vertical groove, and a linkage block is provided on the lifting block, with the auxiliary block fixedly connected to the linkage block; the end of the linkage block away from the lifting block has a transverse groove extending to the side wall of the lifting block, and a stop block is slidably connected in the transverse groove, with a first spring between the stop block and the transverse groove, and a handle on the stop block, which can move laterally in the transverse groove; the side of the V-shaped box near the discharge port has a wall block for abutting against the free end of the stop block, and the free end of the wall block has a stop groove for the stop block to slide into, the stop groove being located on the movement trajectory of the stop block, with the stop block and the stop groove slidingly engaged.

[0011] With the above setup, when the two clamping blocks approach each other, the V-shaped box causes the wall block to move to the right. The right clamping block, through the lifting block, causes the linkage block to move to the left, meaning the wall block and the linkage block approach each other. During the leftward movement of the linkage block, because the auxiliary block moves along the path of the inclined groove, the linkage block, under the action of the auxiliary block, also causes the lifting block to move downward. Therefore, during the approach of the wall block and the linkage block, the wall block approaches the stop block. As the wall block and the stop block continue to approach, the stop block is blocked by the wall block and moves in the transverse groove of the slider. The first spring is compressed, and the stop block moves downward relative to the wall block. When the clamping block is stopped, the stop block and the stop groove are laterally opposite each other. The stop block slides into the stop groove under the action of the first spring, thereby stopping the stop block. Then, the linkage block stops the clamping block, thus strengthening the positioning effect of the clamping block. Furthermore, the stop block sliding into the stop groove can also support the wall block, thereby supporting the V-shaped box and improving the stability of the structure.

[0012] When it is necessary to remove the stop block from the stop groove, simply move the stop block out of the stop groove by using the handle.

[0013] Furthermore, the free end of the stop block is provided with a first wedge surface, and the free end of the wall block is provided with a second wedge surface for frictional contact with the first wedge surface; the end of the linkage block away from the lifting block is provided with a third wedge surface for abutting against the second wedge surface.

[0014] By using the above configuration, the frictional contact between the first wedge surface and the second wedge surface instead of the frictional contact between the wall block and the stop block can improve the stability of their relative motion.

[0015] The first wedge surface is in frictional contact with the second wedge surface, and the second wedge surface is in frictional contact with the third wedge surface. The third wedge surface can support the wall block through the second wedge surface, thereby supporting the V-shaped box and improving the stability of the structure.

[0016] Furthermore, a pipe is provided at the bottom of the clamping block near the vertical groove, and a stop is provided on the inner wall of the pipe; a horizontal block is provided on the side of the V-shaped box away from the clamping block, and an elastic arc block is provided on the horizontal block. Both the horizontal block and the arc block can move inside the pipe. The stop is located on the movement trajectory of the arc block, and the arc block can abut against the inner wall of the pipe after deformation.

[0017] With the above setup, as the two clamping blocks approach each other, the V-shaped box moves closer to the pipe, causing the V-shaped box to pull the horizontal block and the arc-shaped block closer to the pipe, allowing the horizontal block and the arc-shaped block to enter the pipe. As the horizontal block and the arc-shaped block continue to approach the pipe, the free end of the arc-shaped block is stopped by the block, causing the two ends of the arc-shaped block to approach each other, thereby increasing the convexity of the arc-shaped block, so that the convex part of the arc-shaped block abuts against the upper wall inside the pipe. As the horizontal block and the arc-shaped block continue to approach the pipe, when the clamping block stops, the convex part of the arc-shaped block is blocked by the upper wall inside the pipe and undergoes flattening deformation, thereby limiting the position of the V-shaped box and the pipe, and thus enhancing the positioning effect of the clamping block.

[0018] Furthermore, limiting blocks are provided on both sides of the inner wall of the pipeline, and the arc-shaped block can simultaneously abut against the two limiting blocks after deformation.

[0019] With the above settings, after the arc-shaped block is deformed, the protruding part of the arc-shaped block abuts against the limiting blocks on both sides at the same time, thereby limiting the arc-shaped block and enhancing the positioning effect of the clamping block.

[0020] Furthermore, the bottom of the pipe is provided with a bottom hole that communicates with the inside of the pipe; the bottom of the clamping block near the vertical groove is provided with a base plate, a rotating shaft is rotatably connected to the base plate, and a cam is coaxially connected to the rotating shaft. The protrusion of the cam can extend into the inside of the pipe through the bottom hole and abut against the deformed arc block; it also includes a power unit that drives the rotating shaft to rotate as the lifting block moves.

[0021] With the above settings, during the vertical movement of the lifting block, the power unit drives the rotating shaft to rotate, and the protrusion of the cam extends into the pipe through the bottom hole to abut against the deformed arc block, thereby enhancing the limiting effect on the arc block and thus enhancing the positioning effect on the clamping block.

[0022] Furthermore, the power unit includes a gear coaxially connected to the rotating shaft and a rack fixedly connected to the lifting block, with the gear and rack meshing.

[0023] With the above settings, during the vertical movement of the lifting block, the lifting block drives the rack to move synchronously, the rack meshes with the gear to drive the gear to rotate, and the gear drives the rotating shaft to rotate.

[0024] Furthermore, the drilling mechanism includes a bracket fixedly connected to the base, a first cylinder is provided on the bracket, a transverse block is fixedly connected to the output shaft of the first cylinder, and the transverse block is slidably connected to the bracket in the transverse direction; a second cylinder is provided at the bottom of the transverse block, a vertical block is fixedly connected to the output shaft of the second cylinder, a first motor is provided at the bottom of the vertical block, and a drill bit is coaxially connected to the output shaft of the first motor.

[0025] With the above setup, when the metal part is positioned, the first cylinder is activated. The output shaft of the cylinder drives the horizontal block to move horizontally, and the horizontal block drives the first motor and the drill bit to move synchronously. When the drill bit reaches the designated position, the first cylinder is closed to stop the drill bit in the horizontal direction. Then the first motor is activated, and the output shaft of the first motor drives the drill bit to rotate. Finally, the second cylinder is activated, and the output shaft of the second cylinder drives the vertical block to move downward. The vertical block drives the drill bit to move towards the metal part, so that the drill bit acts on the metal part, thereby realizing the drilling process of the metal part.

[0039] A pipe 70 is fixed to the bottom of the clamping block 22 near the vertical groove 52, that is, a pipe 70 is fixed to the bottom of the right clamping block 22.

[0040] The bottom of the pipe 70 has a bottom hole 75 that communicates with the inside of the pipe 70; the bottom of the clamping block 22 near the vertical groove 52 is fixedly connected to a base plate 80, that is, the bottom of the right clamping block 22 is fixedly connected to a base plate 80, and a rotating shaft 81 is rotatably connected to the base plate 80.

The power unit includes a gear 83 coaxially connected to the rotating shaft 81 and a rack 84 fixedly connected to the lifting block 53. The gear 83 and the rack 84 mesh.

[0041] The specific implementation process is as follows:

[0042] In this embodiment, the width of the metal part 90 is greater than the initial spacing between the two clamping blocks 22.

[0043] In use, the metal part 90 is placed on the two clamping blocks 22; the second motor 42 is started, and the output shaft of the second motor 42 drives the bidirectional screw 41 to rotate, causing the two movable blocks 21 to move closer; during the movement of the movable blocks 21, the movable blocks 21 drive the clamping blocks 22 to move synchronously, causing the two clamping blocks 22 to move closer; the two clamping blocks 22 continue to move closer, and when the free ends of the two clamping blocks 22 abut against each other, the second motor 42 is turned off, thereby stopping the bidirectional screw 41, and thus stopping the movable blocks 21, that is, stopping the two clamping blocks 22. At this time, the two clamping blocks 22 also clamp and position the metal part 90; and the through holes 23 on the two clamping blocks 22 are connected, and the through holes 23 are used for the drill bit 17 through hole 23, and for the waste generated during drilling to fall downwards.

[0044] As the two clamping blocks 22 approach each other, the V-shaped box 30 approaches the pipe 70, that is, the V-shaped box 30 moves to the right and the pipe 70 moves to the left; the V-shaped box 30 continues to move, and when the clamping block 22 stops, the V-shaped box 30 also stops, and at this time the turning point of the V-shaped box 30 abuts against the partition 19.

[0045] As the two clamping blocks 22 approach each other, the V-shaped box 30 causes the wall block 60 to move to the right. The right clamping block 22, through the lifting block 53, causes the linkage block 54 to move to the left, meaning the wall block 60 and the linkage block 54 approach each other. During the leftward movement of the linkage block 54, because the auxiliary block moves along the path of the inclined groove 51, the linkage block 54, under the action of the auxiliary block, also causes the lifting block 53 to move downward. Therefore, during the approach of the wall block 60 and the linkage block 54, the wall block 60 approaches the stop block 56, causing the first wedge surface 62 to abut against the second wedge surface 63. As the wall block 60 and the stop block 56 continue to approach each other, the stop block 56 is blocked by the wall block 60 and reverses the slider in the transverse groove 55, compressing the first spring 57, and causing the first wedge surface 62 to rub against the second wedge surface 63. The second wedge surface 63 and the third wedge surface 64 also make frictional contact. The stop block 56 moves downward relative to the wall block 60. When the clamping block 22 is stopped, the stop block 56 is laterally opposite to the stop groove 61. The stop block 56 slides into the stop groove 61 under the action of the first spring 57, thereby stopping the stop block 56. In turn, the clamping block 22 is stopped by the linkage block 54, which strengthens the positioning effect of the clamping block 22. Furthermore, the stop block 56 sliding into the stop groove 61 can also support the wall block 60, thereby supporting the V-shaped box 30 and improving the stability of the structure. In addition, the third wedge surface 64 can support the wall block 60 through the second wedge surface 63, thereby supporting the V-shaped box 30 and improving the stability of the structure. When it is necessary to remove the stop block 56 from the stop groove 61, the stop block 56 can be moved out of the stop groove 61 by the handle 58.

[0046] As the two clamping blocks 22 approach each other, the V-shaped box 30 moves closer to the pipe 70, causing the V-shaped box 30 to pull the horizontal block 72 and the arc-shaped block 73 closer to the pipe 70, allowing the horizontal block 72 and the arc-shaped block 73 to enter the pipe 70. As the horizontal block 72 and the arc-shaped block 73 continue to move closer to the pipe 70, the free end of the arc-shaped block 73 is stopped by the stop block 71, causing the two ends of the arc-shaped block 73 to move closer together, thereby increasing the protrusion of the arc-shaped block 73, so that the protruding part of the arc-shaped block 73 contacts the pipe. The upper wall inside 70 abuts against each other; the horizontal block 72, the arc-shaped block 73 and the pipe 70 continue to approach each other. When the clamping block 22 stops, the protruding part of the arc-shaped block 73 is blocked by the upper wall inside the pipe 70 and undergoes flat deformation, so that the two sides of the protruding part of the arc-shaped block 73 abut against the limiting blocks 74 on the left and right sides at the same time. This can achieve the limiting of the arc-shaped block 73, and then the clamping block 22 is limited by the horizontal block 72 and the V-shaped box 30, that is, the positioning effect of the clamping block 22 is strengthened.

[0047] During the downward movement of the lifting block 53, the lifting block 53 drives the rack 84 to move synchronously. The rack 84 meshes with the gear 83, causing the gear 83 to rotate. The gear 83 drives the rotating shaft 81 to rotate, and the rotating shaft 81 drives the cam 82 to rotate. When the clamping block 22 is stopped, the protrusion of the cam 82 extends into the pipe 70 through the bottom hole 75 and abuts against the deformed arc block 73. This can enhance the limiting effect on the arc block 73, thereby enhancing the positioning effect on the clamping block 22.

[0048] When the metal part 90 is positioned, the first cylinder 12 is activated. The output shaft of the cylinder drives the horizontal block 13 to move laterally. The horizontal block 13 drives the first motor 16 and the drill bit 17 to move synchronously. When the drill bit 17 reaches the designated position, the first cylinder 12 is closed to stop the drill bit 17 in the horizontal direction. Then the first motor 16 is activated, and the output shaft of the first motor 16 drives the drill bit 17 to rotate. Finally, the second cylinder 14 is activated, and the output shaft of the second cylinder 14 drives the vertical block 15 to move downward. The vertical block 15 drives the drill bit 17 to move towards the metal part 90, so that the drill bit 17 acts on the metal part 90, thereby realizing the drilling process of the metal part 90.

[0049] During drilling, metal particles and powder fall onto the bottom left side of the V-shaped box 30. The metal powder then falls through the sieve hole 31 into the collection tank 18, where it is located on the left side of the partition 19. Meanwhile, the metal particles, guided by the bottom left side of the V-shaped box 30, move towards the bottom right side of the V-shaped box 30, eventually falling from the discharge port 32 into the collection tank 18, where they are located on the right side of the partition 19. This process completes the classification and storage of metal powder and particles, improving work efficiency and preventing hand injuries during manual screening.
